Potential Truffle Ground Map

This is a new map representing potential truffle ground in France. Given its scale, the different areas have been simplified and are not outlined with great precision.

 However, the advantage of this overall view, is that it enables us to realise that France offers enormous truffle-producing potential.

This map takes into account three main factors : geology, altitude and the pH content in the soil, and it is the result of our own findings and those of numerous colleagues. 

As opposed to other maps showing potential truffle ground, and for the sake of clarity, we have purposely not distinguished between soils favouring the Black Truffle (Tuber Melanosporum), the Burgundy Truffle (Tuber Uncinatum) or the Mesenteric Truffle (Tuber Mesentericum).

The differences and physical properties in soil types favouring one or other of these three species, are often so minimal in one same ground, that they would be impossible to illustrate on a map of this scale.

However, for those who wish to have a general idea, we could say that on the whole, Autumn Truffles grow all over eastern France, in the Auvergne region and at a certain altitude in limestone massifs, and the Black Truffle grows all over southern and western France.
